isue in landed cost relationship map

hi all, i have found one issue..

after creating landed cost document when we see relationship map, the currency sign is showing in dollar but the amount which is showing is actually in Indian rupees....

For eg: landed cost of document is 1000$ so when we see a relationship map

its showing $620000.

actually 620000 is document value in Indian rupees.

so is there any setting for this to change currency in relationship map or show  amount in dollar etc????

rgrds,

mahesh
